Safety instructions 2.2 Obligations 2.2.1 Operator obligations Determine responsibility Operator obligations The operator has to define the personnel responsibility and ensures that only instructed, or skilled persons may work at the vacuum system. This applies in particular to connection, assembly and maintenance work and fault remedy. The operator has to ensure compliance with the prescribed limits, the specified ambient conditions, and the distance around the vacuum pumping unit. For commissioning, the operator has to instruct the network connection by a local electrician. It is the operators obligation to take necessary precautions, in particular for machines which run twenty-four-seven without constant supervision, e. g., fire protection. 2.2.2 Staff obligations Staff obligations For workings that require protective clothing, wear your personal protection equipment which is specified by the operators regulations. In case of error the personnel (staff) is obliged to inform the responsible supervisor immediately. In case of improper state of the machine it has to be secured from being switched on again. Work in a safety-conscious manner Personal responsibility Personal safety has top priority! Processes which create a potentially hazardous situation are not allowed. > > Use the vacuum pumping unit only, if you have understood the manual and the function principle of the machine.

Safety instructions 2.5 ATEX category Installation and explosive environment Installation and operation in areas where explosive atmosphere can occur is not allowed. ATEX category ATEX equipment labeling VACUUBRAND products with label II 3G IIC T3 X Internal Atm. only; Tech. File Ref.: VAC-EX01. VACUUBRAND products which are labeled with ` have an ATEX approval 3 G; i. e. flammable substances as mixture with air: Pumped gas or vapor. >Use > the VACUUBRAND product only when it is in proper working condition. ATEX category and peripherals ATEX approval 1 is only valid for the internal, wetted parts area (vacuum sensor), not for the environment of the controller. The ATEX category of the VACUUBRAND product is dependent on the connected peripheral devices. Peripherals and connected devices to the controller need to have the same or higher ATEX approval. Without concordant categorization of peripherals, the specified category of the VACUUBRAND equipment loses its validity. Prevent ignition source The operation of venting valves is only permitted if thereby explosive atmospheres normally do not occur in the interior wettet part of the VAC 24seven or, if they do occur, are likely to do so only infrequently and for a short period. >If > necessary vent with inert gas. After any intervention at the equipment, e. g., repair or maintenance the ultimate vacuum of the vacuum pump(s) hast to be checked. Only if the unit achieves its specified ultimate vacuum is the pump s leak rate low enough to ensure that no explosive atmospheres will occur in the interior of the equipment. After any intervention at the vacuum sensor, the leak rate of the equipment has to be checked.
